When you are searching for a security camera for your business, be aware that there are many choices, ranging from simple, single-camera systems to kits including multiple cameras along with monitors, digital recorders and hard drives for storing files. Most businesses benefit from having at least two cameras on site; however, consider the following when making your decision.

There are four primary types of security cameras available. Box cameras are the most common. They are visible, which tends to deter would-be criminals, and easily customized with a number of interchangeable lens types. Bullet cameras are similar to box cameras in that they are visible and accept interchangeable lenses; however, they also include zoom lenses and vary widely in size, from compact to large. Dome cameras are more subtle than box cameras and most bullet cameras as well. Finally, pan/tilt/zoom, or PTZ cameras, are capable of swiveling to offer a 360-degree field of view with just one camera. Most are remote-controlled.

Once you choose a camera type, consider whether you need an indoor or outdoor model. Outdoor security cameras are generally more expensive as they are built to withstand extreme temperatures, precipitation and wind. Some outdoor cameras are disguised to appear to be rocks or other objects that most people do not suspect are cameras.

Determining whether you need one or multiple cameras involves not only the layout and size of your business location but the traffic it typically experiences. Most businesses are well served by four cameras mounted near entryways and potential access points as well as near any inventory or cash registers or safes.
